Consider the rectangular control volume abcd given by the dashed line in Fig8.3. The shock wave is inside the control volume 考虑矩形控制体abcd如图8.3虚线所示,激波在控制体内 We apply the integral form of conservation equations to this control volume.我们对这个控制体应用积分形式动量方程 In the process, we observe four important physical facts about the flow given in Fig.8.3:在进行过程中,注意图8.3给出的四个 重要物理事实: 1. The flow is steady,ie./at=0.流动是定常的 2. The flow is adiabatic: no heat is added or taken away from the control volume.流动是绝热的,没有加入和带出控制体的热 量 3.There are no viscous effects on the sides of the control volume 控制体的边界上没有粘性的作用。 4 There are no body forces;f=0。没有体积力。Consider the rectangular control volume abcd given by the dashed line in Fig.8.3.
